The use of internet growing faster day to day and the need
to display multimedia contents on the internet become necessary. Intellectual
property right; documents are not fast information but property. YouTube, face book, Torrents, pirate bay such other video,
audio, image, documents resource websites are now became water and food for youngsters across the globe so it
is necessary to protect the rights of authors, so digital protection is necessary and in-evitable.

MATLAB code for Combined DCT+DWT Image Watermarking.
The proliferation of digitized media due to the rapid growth
of networked multimedia systems, has created an urgent need for copyright
enforcement technologies that can protect copyright ownership of multimedia
objects. Digital image watermarking is one such technology that has been
developed to protect digital images from illegal manipulations. In particular,
digital image watermarking algorithms which are based on the discrete wavelet
transform have been widely recognized to be more prevalent than others.
MATLAB code of LSB based Video Steganography.
Video Steganography is an art and science of hiding images
or text within the video file. The LSB approach is used
along with the Masking Filtering and Transformations techniques to hide the
secret image or any other files in video.
Data Hiding Algorithm:
Following diagram shows Data embedding algorithm in details.
